Abstract
n-부탄의 산화적 탈수소화 반응을 위한 Cr 촉매가 연구되었다. 촉매의 제조는 메조포러스 물질인 SBA-15와 γ-alumina 지지체로 사용되었고 지지체의 표면 위에 Cr 산화물을 담지시키는 방법은 함침법이 사용되었고, Cr의 분산성을 높이기 위하여 구조 증진제로 Ti, Zr를 분산시킨 위에 Cr을 담지하여 특성분석 하였다. 촉매특성은 XRD, FT-IR, UV-Vis, ICPAES, SEM, TEM 등을 이용하여 분석하였다. Cr 촉매에서 넓은 표면적을 가진 지지체의 효과는 전환율에 큰 차이를 보이지 않고 Ti, Zr이 증진제로 사용된 촉매의 경우 trans-2-부텐의 선택도가 높아짐을 보였다.
Oxidative dehydrogenation of n-butane over mesoporous Cr catalysts were studied. Catalysts were prepared by Cr impregnated method over Ti or Zr dispersed mesoporous support such as SBA-15, γ-alumina and characterized by XRD, SEM, TEM, FT-IR UV-Vis and ICP-AES. The effect of high surface area was not noticed appreciably in terms of conversion, but for Cr catalysts with Ti and Zr-incorporated on SBA-15 and γ-alumina. showed high selectivity of trans-2-butene.
